we see trolling sometimes in elected officials, too. when a politician says something deliberately provocative in front of an audience because they're banking on firing up a smaller group of people who enjoy the way that speaker can make that other audience feel. congressman steve king is kind of a permanent troll. >> we could also electrify this wire with the kind of current that wouldn't kill someone but would simply by a discouragement from them. we do that with livestock all of the time. >> comparing imgrants to livestock and using a visual aid to do so on the house floor. here's another. >> a poet once said life can be a challenge, life can seem impossible, but it's never easy when there's so much on the line. >> he was trolling the entire democratic process at that point. here's oolt. trolling. congressman allen west, former congressman allen west begging america please be out raged by me, please condemn me. i live to cause pointless out rage. i am a troll. the thing about trolling is that the troll, by definition, is not serious.
